Remediation

What is land remediation?
Remediation involves identifying, treating, and managing contamination in soil or groundwater to make land safe and suitable for construction. This is a key step for brownfield development, infrastructure delivery, and any project involving legacy industrial land.
Our team supports clients through every stage, from early assessment and risk review, to on-site treatment and regulatory sign-off.

Remediation is required when land is affected by contamination from previous use (e.g. fuel, heavy metals, asbestos), making it unsuitable or unsafe for development without treatment.
-
What are the main methods used?
This depends on the type of contamination. Common methods include excavation, stabilisation, soil washing, and biological treatment.
-
Who determines when a site is safe?
Validation is signed off by the local planning authority, usually in consultation with an environmental consultant and the Environment Agency.
